It is from their own self-description.
"It is from their own self-description."
I'm sorry, but it's an unfortunate choice of words for their description. Google "Vigilance Committee" and you'll see what I mean.
The Vigilance Committee of 1856 was the very source of the word "vigilante." By choosing this word in their description of themselves, they have invited the use of the word "vigilante" for their group. It's sad.
Anyone with a knowledge of history knows this. President Bush knows this, and chose to use the word "vigilante," probably at least partly based on the organization's description of itself.
Very bad choice. They have a good cause, but they hurt themselves from the first line on their web site.
